VDroop mod works quite well though, It took me about 20 minutes of work to complete it on the mobo, another 30 or so to take it all apart and put it back together. The results were great for $2 in parts and an hour of my time.

Budwise, if your PWM temps are getting that high I'd put a small fan on the PWM heatsink or better yet, take a look at Ace's signature and follow the heatpipe mod link. Because you have a quad core, the PWM area will be under more stress and generating more heat.
